This is one Mathematics question for my pupils to attempt before the start of PSLE. If you are not my pupil, please feel free to solve the question too. Post your solutions in the comment space if you wish to. Solutions will be posted tomorrow. Have fun! 🙂
There are 600 children in Group A and 30% of them are boys.
There are 400 children in Group B and 60% of them are boys.
After some children are transferred from Group B to Group A, 40% of the children in Group A and 60% of the children in Group B are boys.
How many children are transferred from Group B to Group A?
